An serious/obsessive reader of the Twilight Saga by Stephenie Meyer, one leap above Twilighters.

The difference between being a Twilighter and being a Twihard, is that Twihards have embraced a new Twiligion... er.... I mean, religion based on Twilight. They live and breath Twilight. Most Twihards are for Edward and Bella. Therefore, those Twihards are all for true love & love at first sight. Point out one thing to a Twihard, and they can relate it to Twilight instantly. Savage and wild, they need every single thing to be perfect in the upcoming Twilight movie.

40. You refer to to Robert Pattinson as RPattz or Spunk Ransom.
41. And finally, you are willing to spend hours on an essay/word/website that probably won't ever be read, just cause you want to talk about Twilight.

While Twilighters are open to changes with the book in the upcoming Twilight movies, Twihards are very conservative, and hate whenever something changes.

Those Twihards got really pissed off at MTV for spending a Tuesday interviewing The Bella Cullen Project.

A combination of the words "Twilight' and "Die-Hard", Twihards (usually young females) are obsessive fans of the "Twilight Saga" series of books by author Stephenie Meyer, and the film adaptations. Twihards embrace all things Twilight with religious zeal, daily visiting fansites, quoting dialoge from the series, and stalking (online or in person) the films' stars, especially on the Vancouver BC movie set. Most Twihards are "Team Edward", although the self-declared sub-category "Team Jacob" also qualifies for the Twihard designation. Comment or remark to a Twihard, and she can relate it to Twilight instantly.

An individual that will more than likely take extreme and hostile actions towards any other individual that either has no interest in the Twilight series or believes it to be a collection of filth on paper that could have been used for a better purpose such as wiping one's bum.

A human being who is a fan of Stephenie Meyer's 'Twilight Series', consisting of 'Twilight', 'New Moon', 'Eclipse', and 'Breaking Dawn'. Twi-Hards are usually quite addicted to the series, and would be considered 'obsessed' by some. (Formerly known as 'Twilighters')

On the set of the "Twilight" movie, Twi-Hards have been seen camping out so that they can both see the actors and perhaps sneak onto the set.

A mixture of the words 'Twilight' and 'Try-hard'. It is one of many names given to the fanbase of Stephenie Meyer's series of books, Twilight, New Moon and Eclipse (and Breaking Dawn, not yet released).

"Oh my god, I can't wait until the Twilight movie comes out in December!!!"
"You are such a Twihard."
